We recommend giving it a a few weeks to a month to allow your body to fully disperse the years of muscle tension (especially if it is your first time on a Gel Mattress). However our amazing customer service team is here to help you as well!

Yes, we highly recommend having a foundation as keeping any mattress on the floor for long periods of time will start to build mold, Good News is that our Dynasty Beds can be used with any foundation!

The weight is dependent on the size and thickness of the mattress, however they are generally 30-100 pounds and comes compressed and vacuum sealed neatly into a compact box, making it a breeze to move around the house!

Not necessarily, as all of our mattresses have an easy access cover zipper to machine wash the covers, But we do suggest rotating the mattress every 1-3 years to maintain it's peak performance!
